I have a 2003 GReddy Twin Turbo Z. It runs fine at 5 lbs of boost. It was boosted in August, and I haven't had problems with it really.

Today I drove it from home to the grocery store, about 2 miles. Then I drove it to work, another 10 miles or so. I try and leave work, and the car starts, and then dies. It does it again, turns on, then dies right away.

I figure it isn't getting gas. So I start the car with my foot on the gas peddle. It started up, but very jerky. It has gas in it, right above a quarter tank. When I am at a light I have to leave it in neutral and give it gas. What is wrong with it? ANy ideas? I don't want to pay a dealership $90.00 an hour to tell me it's something when this could be something I can fix on my own.

HELP!

 

Start looking for loose fittings. My Vette did something similar (didn't die on me, but was very jerky). Ended up being a loose MAF connection.

 

Once you go fi I really wouldnt take it to the dealership I wouldnt go anyway but you know

 

Well, I am taking it to an Auto Parts store today to see if it's throwing a code. Then I will go from there.

 

Sounds like you have a vacuum leak somewhere. Check all your pipes.

 

^^ Thats what I was thinking...

Check all your hoses/fittings

 

It's drivable. I need to keep my foot on the gas to start it and at idle. It is the TPS sensor. How easy is that to replace?

 

it could be a vacuum leak but also check your air flow sensor but first check if the ecu is throwing codes. good luck

 

I'm thinking vacuum leak. Wouldn't a faulty maf have problems through out the rev not just idle. The tps sounds like that could be it also but once you get past the faulty part of the tps then it should run like normal.

 

i had this problem i changed my plugs and cleaned my MAF gave half *** cleaning to the throttle body and wiped it down with a rag. now my car starts up so fast and idles smooth and nice
